Amphibians do not have the waterproof skin that amniotes (reptiles, birds, and mammals) do. If they are not wet, they can dry out and die, especially because many types of amphibians breath partly or entirely through their skin.
Amphibians also need an aquatic environment in order to breed, because their eggs and young must be in water, or they will dry up and die.
Most amphibians are semiaquatic, spending part of their lives in water and part on land.
Amphibians don't have amniotic eggs - their eggs don't have shells, and they have to be laid in water. In general, amphibians are more dependent on water, most of them having aquatic larvae and having to keep their skin moist even as adults in order to breathe through it.
Aquatic larvae that breathe with gills and as terrestrial adults that breathe using lungs and skin
no, they are the most stable and have the most variety of fish and aquatic mammals than anywhere else in the world.
Yes. Most amphibians cannot go far from a moist environment as they have difficulty maintaining their body moisture.
Amphibians are of the class Amphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Amphibians typically start out as larvae living in water.
Because,reptiles are land creatures. Their skin is drier than amphbians. They like to bask in the sun. If amphibians basked in the sun like that,they would dry out!
Their skin allows them to live in water as well on land and most species have colors helping them to blend in their environment.
In most species Amphibians hatch as aquatic larvae with gills and then undergo metamorphosis into four-legged terrestrial adults with lungs for breathing air.
The origin of the term Amphibia comes from Latin meaning 'two lives' (land and water based), as most amphibians spend a larval stage as aquatic water breathers.
Mollusks live in most environments ranging from arctic oceans, to mountainous terrain. They are both aquatic and terrestrial.
Technically speaking, every organism on earth is dependent on water. In order for something to live, they need water because it is a main component of every living thing. Amphibians are especially dependent on water because most have skin that takes in water from their pores and they also need it to cool off.
